Punk rock skeleton demos mind control system

Who says punk is dead? In the video above, a skeleton with a mohawk is helping to visualise how a new neural implant device reads brain signals and interprets them to control a prosthetic arm. The yellow spikes radiating from the skeleton's head represent the firing of motor neurons in the brain. Each neuron is tuned to recognise a different direction in space, so as the arm moves, the spikes change to reflect the changing direction. By adding together the output of all the neurons, the direction of the arm's movement - represented by the blue arrow - can be predicted.
